ABSTRACT

A collar for fitting over at least a portion of the housing of a fuel delivery nozzle. The collar comprises a main body, an arrangement for securing the main body to the housing, and a collar portion shaped to mateably engage around a portion of the housing and arranged to engage the main body.

This application is the National Stage of International Application No.PCT/GB96/02868, filed Nov. 21, 1996, which claims the benefit of BritishApplication No. 9523793.9, filed Nov. 21, 1995.

The present invention relates to a collar/display device for a fueldelivery device. In particular, the invention relates to a collar thatcan be fitted over at least a portion of a housing of a petrol dischargeunit and/or a splashguard for the unit.

Most petrol pumps are provided with a concealed stationary pump forpumping petrol from an underground tank through a fuel pipe to a handheld and manually operable fuel delivery device. A typical fuel deliverydevice is shown in FIG. 1a. Such devices generally comprise thefollowing main parts: a nozzle 1 through which fuel is delivered ordischarged; a housing designated generally as 2 which houses a fuelmetering valve, the housing having a knuckle portion 3 containing meansfor adjusting the valve; and a handle 4 which is held by the persondispensing the fuel. The handle usually has a trigger (or lever) 5 foradjusting the rate of fuel discharge and a finger guard. In addition asplashguard 6 may be provided on the nozzle to prevent fuel delivered bythe device splashing back from the tank being filled. A commonly usedfuel delivery device of the type shown in FIG. 1a is the ZVA (a TradeMark) nozzle available from Elaflex Limited of the United Kingdom.Further well known devices include the OPW (a Trade Mark) nozzle fromOPW Fueling Components Europe (BV) of the Netherlands, the Huskey (aTrade mark) nozzle available from Huskey Corporation of Tucson, Ariz.,USA and the EMCO Wheaton (a Trade Mark) nozzle available from EW FuelManagement Limited of the United Kingdom.

Although the type of fuel is often displayed on or near the petrol pumpitself, with the increasing variety of fuels available for motorvehicles there is a continuing need to ensure that a motorist wishing torefill with fuel does so using the correct type of fuel. Not only ispetrol available in various grades such as four-star, but also asunleaded petrol (or lead-free) as well as special unleaded fuel that isintended to give improved performance (sometimes termed super-unleaded).

When one additionally considers diesel, this results in many differenttypes of fuel being commonly available at petrol filling stations. It isimperative that the motorist fills the tank of his motor vehicle withthe correct type of fuel (since most engines will only run on one type)and this is all the more reason why the correct fuel type needs to beclearly indicated.

In order to ensure that the correct type of fuel is chosen, the fueldelivery device is often labelled with the type of fuel it delivers inaddition to the pump itself. Furthermore, the fuel line may be colourcoded (for example, red for leaded petrol, green for unleaded and blackfor diesel). In addition the housing is usually covered by a flexiblerubber shroud or "scuffguard" which usually covers the knuckle portionthat contains the valve adjustment means.

The scuffguard is sometimes colour coded depending upon the type of fuelto be dispensed by the device (as described previously).

One known way of providing an additional indication of the type of fueldelivered by the delivery device is to replace the scuffguard altogetherwith a flexible cover having an internal configuration suitable to fitover the housing. The replacement scuffguard includes a generally planarupper portion onto which information material such as a suitably shapedpiece of paper, plastic or cardboard having the information printedthereon is placed and retained by a clear cover having side walls whichclip over the planar portion of the replacement sleeve, retainingprojections on the side walls mating with corresponding recessesprovided on the sleeve. Various problems are associated with thearrangement. In particular it is difficult to remove and replace theoriginal scuffguard and by doing so, manufacturing or source informationfound on the original scuffguard is lost. In addition the cover can beeasily removed and the information material lost either inadvertently orby acts of vandalism.

An improvement to the system comprises a collar which is configured tofit over all or a portion of the scuffguard and be retained in place,for example by a clip or other suitable retaining means. Such anarrangement is more easily removable and interchangeable.

Recently, a new type of fuel delivery device has been introducedincluding a vapour recovering nozzle. The general structure of thevapour retrieving nozzle device is similar to that of the conventionalfuel delivery device shown in FIG. 1a. In addition, however, in onevariant the nozzle 1 is surrounded at its end nearest the housing 2 by acoaxial cylindrical sleeve projecting from the housing 2. The precisemanner of operation of the vapour retrieval device is well known and isnot of immediate relevance to the present invention. However, insummary, as fuel is delivered by the device into the petrol tank of avehicle, fuel vapour already in the tank of the vehicle is displaced outof the tank and is channelled through the passage between the nozzle andthe surrounding cylindrical sleeve and stored in an appropriate tankprovided at the fuel station. Alternatively the nozzle can includeperforations along its length for retrieving vapour.

An OPW nozzle of the vapour recovery type is shown in FIG. 1b. As willbe seen it includes an exaggerated knuckle portion 3 extendingsubstantially above the handle 4, to house the vapour recoverymechanism. The knuckle portion 3 is also of greater length than in FIG.1a, and extends below the device, filling in the space between the frontend of the finger guard and the nozzle 1. FIG. 1c shows the OPW standardnozzle in which, it will be seen, the knuckle portion 3 is slightly lessexaggerated.

The vapour recovery fuel delivery devices, like the conventional fueldelivery devices, are provided with a scuffguard. However the profile ofthe scuffguard differs between the devices, principally because of thediffering pumping and dispensing mechanisms found in the housing in eachcase. In particular, the profile of the scuffguard on the vapourretrieval device is rather fuller as the vapour recovery mechanism isprovided at least partially in the housing. In the commonly used ZVAvapour recovery-type device the housing, when viewed from the side ismore convex or bulbous in the upper front region than the standard ZVAdevice.

Accordingly a problem arises with the known devices as existingarrangements are not suitable for use with both types of device. Thescuffguard replacement cover for example must be remoulded to fit thevapour recoverytype delivery device, as must the improved collararranged to fit over the scuffguard.

In addition, because of the provision of the vapour recovery sleevesurrounding the nozzle on the vapour retrieval device, or thealternative configurations, the existing scuffguard replacementarrangements may not even fit onto the vapour retrieval device as theyare obstructed by the vapour retrieval sleeve.

According to the invention there is provided a collar for fitting overat least a portion of the housing of a fuel delivery device wherein thecollar comprises a main body, means for securing the main body to thehousing and a collar portion shaped to mateably engage around a portionof the housing and arranged to engage the main body. As a result thecollar can be fitted firmly and securely to the housing. The collarportion preferably comprises a splashguard, allowing an advantageousduplication of function.

The collar portion may be arranged to mateably engage around the housingof a conventional fuel delivery device or around the housing of a vapourrecovery fuel delivery device. Thus, only the collar portion needs to bechanged dependent on the type of delivery device, the other componentsbeing commonly usable.

The collar portion may be shaped to mateably engage around the housingof a fuel dispensing device, the housing including a scuffguard. Thecollar can thus be placed over the delivery device without the need toremove the scuffguard.

The main body may include a portion for displaying information, and aprotective cover may be provided for the information display, andwherein the protective cover is configured to be retained within asurrounding wall of the main body. The cover is thus substantiallytamper-proof. The protective cover may be retained in the main body bydetent means, the information display obscuring the detent means tofurther discourage tampering. The main body may include channels throughwhich the protective cover may be pushed from the underside of the mainbody to detach the protective cover from the main body. Thus theinformation display may be simply changed by authorised personnel.

The main body may be secured against the housing by a tie encircling thehousing.

According to the invention there is further provided a kit for a collarfor fitting over the housing of a fuel dispensing device, the kitcomprising a main body, means for securing the main body to the housingand either of a first or a second collar portions arranged to mateablyengage around the housing of a respective first or second type of fueldelivering device. The first collar portion may be shaped to mateablyengage around the housing of a conventional fuel delivery device and thesecond collar portion may be shaped to mateably engage around thehousing of a vapour recovery fuel delivery device.

According to the invention there is further provided a display devicefor a fuel delivery device, the display device including a main bodysecurable to the fuel delivery. device for displaying information and aprotective cover releasably attachable to the main body for covering theinformation display wherein the protective window is received within themain body.

According to the invention there is further provided a method ofattaching a collar to the housing of a fuel delivery device, the collarincluding a main body, securing means and a collar portion, in which themain body is secured to the housing by the securing means, the collarportion is placed around the nozzle of the fuel delivery device andbrought into mateable engagement around a portion of the housing andinto engagement with the main body.

According to the invention there is further provided a method ofchanging the information display on a collar for a fuel delivery devicewherein the collar comprises a main body, an information display and aprotective cover for the information display surface detachably fastenedto and received within the main body, comprising the steps of pushingthe protective cover out of engagement with the main body through achannel from the underside of the main body.

According to the invention there is further provided a splashguard for afuel delivery device having a delivery nozzle, the splashguard includinga nozzle receiving aperture situated eccentrically substantiallyadjacent an edge of the splashguard.

Throughout the specification the terms "front" and "forward" relates tothe fuel delivery nozzle end of the arrangement and other terms are tobe construed accordingly. Reference numerals, where appropriate, relateto the same features throughout the specification.

The various parts of the collar according to the present invention areshown in FIG. 2 in relation to a vapour recovery-type fuel deliverydevice 7 including a nozzle 8, a vapour retrieval sleeve 9 and ascuffguard 10.

The collar comprises a main body 11, a splashguard 12, an informationdisplay sheet 13, a protective cover 14 and a securing means 17.

The main body 11 is moulded from a petrol resistant, inflammablematerial of any known type and, as shown in FIG. 5, includes aperipheral wall 18 defining a central aperture with internal ribs 15providing structural support and defining a surface on which theinformation display surface 13 can rest. Viewed from above, theperipheral wall of the main body 11 comprises two long walls terminatingat a squared or rounded (in other embodiments not shown here) end 19 atthe front of the main body and a rounded end 20 at the rear of the mainbody. In the embodiment shown a skirt 16 depends from the peripheralwall 18 as may best be seen in FIG. 5a and is configured to enclose aportion of the scuffguard 10. As may be seen in FIG. 5a the skirt 16depends only from the front portion of the main body 11 in order toclear the portion of the scuffguard 10 covering the trigger guard. Ofcourse, dependent on the type of fuel delivery device the skirt may beomitted, as shown in FIGS. 5e and 5f. This configuration is suitable,for example, for the nozzle types shown in FIGS. 1b and 1c havingexaggerated knuckle portions 3 extending below the device. Theembodiment shown in FIGS. 5e and 5f includes a continuously, slightlycurved display surface 13 as discussed in more detail below.

Referring to FIGS. 5c and 5d it can be seen that viewed from the frontor rear the main body 11 is of generally an inverted U-shape, theoptional skirt portion 16 comprising the downward limbs of the U-shape.Accordingly the main body may be simply placed over the scuffguard 10.The main body 11 is secured to the fuel delivery device 7 by anysuitable securing means shown generally as 17 in FIG. 2, for example ahose clip, a reusable cable tie. The securing means 17 are preferablyreleasably fastenable in order to facilitate replacement of thearrangement as a whole. The securing means 17 pass around a formationcontained within the peripheral wall 18 of the main body 11 and aroundthe scuffguard 10 and, in use is hidden by the information display sheet13. An alternative securing means as discussed in more detail belowcomprises hook-type projections arranged to engage between for examplethe scuffguard and the fuel delivery device, where appropriate.

The main body 11 has a downwardly curving rear portion when viewed fromthe side and may also be configured to define two information displaysheet supporting surfaces to support a two-part information displaysheet 13 comprising parts 13a and 13b. The information display sheet 13may, in addition to or alternatively to displaying informationconcerning the fuel dispensed by the fuel dispensing device also displayadvertising material or other informational material. For example asmaller information display sheet 13a could display information relatingto the fuel dispensed by the device and could be permanently fixed inthe main body 11 whilst larger information display sheet 13b could beremovable and display advertising material.

The information display sheet 13 is retained in the main body 11 bymeans of a protective cover or window 14. The protective cover 14 servesnot only to protect the information display sheet 13 from damage by theelements and petrol splashes but also prevents the information displaysheet 13 from being removed from the main body 11 either inadvertentlyor by vandals. It is manufactured in a transparent petrol resistantmaterial of a known type and may be, for example, of 2 mm wallthickness. The cover 14 includes a cover surface 21 through which theinformation material may be viewed and shaped to match the profile ofthe main body, including as shown in FIG. 6b a downwardly curving rearportion which is generally shaped to fit snugly within an upper recessof the main body 11 bounded by the peripheral wall 18 of the main body11. The protective cover 14 further includes a depending wall 22 runningaround its periphery and provided with projections arranged to mate withcorresponding recesses 24 in the peripheral wall 18 of the main body 11.Alternatively, as discussed in more detail elsewhere in thespecification, the recesses may be formed on the cover wall 22 and theprojection on the body wall 18. In either case a clip-in lockingmechanism is provided. Because the protective cover 14 fits within theperipheral wall of the main body it presents an obstacle to vandalsattempting to remove the cover 14, in particular because when the cover14 and information display sheet 13 are in place the means by which thecover 14 is retained in the main body 11 cannot be seen. When, however,it is desired to replace the information or advertising materialcontained on the information display sheet 13 the protective cover 14may be easily removed from the main body 11 by pushing up through theunderside of the main body 11 using the aperture between the ribs 15.The message sheet 13 can be simply removed in a similar manner.

Referring to FIGS. 3a, 3b, 4a and 4b, the splashguard 12 is manufacturedfrom a petrol resistant material of a known type. Generally the materialof the splashguard 12 will be more flexible than that of the main body11 in order to avoid damage being caused to user's vehicles when thesplashguard comes into contact with the vehicle body. The splashguard 12includes a front, generally planar surface 30 of suitable dimensions(e.g. roughly 100 mm²) to catch any splashes coming from the petrol tankbeing refuelled, and a rear projecting portion or lug 31. An aperturepasses through the front 30 and rear 31 portions enabling thesplashguard 12 to be placed over the nozzle 8 and vapour retrievalsleeve 9 of the fuel delivery device 7. The splashguard 12 is furtherinternally shaped to cover snugly a front portion of the scuffguard 10,an internal surface of the projection 31 mating with the externalsurface of the portion of the scuffguard 10. The projecting portion 31also includes a projecting lip 32 on its rear upper face. When thesplashguard is placed over the nozzle 8 and vapour retrieval sleeve 9 ofthe fuel delivery device 7, and is brought into engagement with thefront portion of the scuffguard it also engages with the main body, therear projecting rib 32 engaging a corresponding recess in the main bodyportion to retain the parts in position and in engagement. Theprojection 31 is shaped externally to mate with a portion of the mainbody 11. As a result, the main body 11 is held securely in place againstthe scuffguard 10 with little or no play.

Accordingly the splashguard 12, as it is configured to fit snugly overthe front portion of the scuff guard retains the arrangement as a wholefirmly in place on the scuffguard. As can be seen from FIGS. 4a and 4b,in one embodiment the configuration of the splashguard 12 is ratherdifferent if the arrangement is to be placed on a conventional fueldelivery device. In that case the rear projection 31 includes an upperrear extending snout 33. This additional portion 33 is required to "fillin" the profile of the conventional device scuffguard, which is lessbulbous than that of the vapour retrieval-type scuffguard, in order toensure a secure fit for the information display arrangement as a whole.Accordingly, in order to modify the information display arrangementdependent on which type of fuel delivery device is required, it is onlynecessary to vary the type of splashguard used. Thus significantremoulding or retooling costs and problems are avoided and it is simplynecessary to manufacture only two types of splashguard, a single commonmain body being used in either case.

FIG. 7 shows the collar designated generally as 40 in position on thefuel delivery device 7. In order to mount the collar 40 in position, themain body 11 is first placed on the scuffguard 7. The splashguard 12appropriate to the type of fuel delivery device 7 is slid over thenozzle and into engagement with the main body 11 and the scuffguard 7and the fastener 17 is then tightened to ensure that the collar 40 isheld firmly and securely in place.

FIGS. 8a to 8c show an alternative configuration for the main body. Ascan best be seen from FIG. 8b the main body 50 includes a displaysupport surface 51 onto which a protective cover 52 fits. The displaysurface 51 and protective cover 52 are, in cross-section, continuouslycurved across a shallow arc.

The protective cover 52 clips on to the main body, and is removablysecured thereto, by means of retainers 54. The retainers 54 compriseprojections on the main body which mate with corresponding recesses in aperipheral wall or skirt of the protective cover 52. As a result theprotective cover 52 is yet more firmly secured to the main body 50, andwill discourage vandalism whilst allowing quick and simple removal byauthorized personnel. As a result of the resilience of the materialforming the protective cover 52 (for example clear plastics material)the protective cover 52 is simply slid into engagement with the mainbody 50, with the peripheral wall or skirt engaging a correspondinggroove in the main body, and the retainers 54 snapping into matingengagement.

As can best been seen from FIG. 8c the main body 50 includes one or morehooks (in the preferred embodiment, 4), each hook being designated 56.These hooks accommodate certain nozzle types on which there are suitablepoints of hold for the hooks 56. In that case the main body as a wholecan simply be snapped onto the nozzle with the hooks engaging under thecorresponding holding points on the nozzle. For example in some nozzletypes the scuffguard does not fully engage the nozzle head at all pointsbut leaves a gap into which the hooks 56 can enter. As a result the mainbody can be quickly and securely engaged on the nozzle. An alternativepossibility is to provide a "sub-frame" (not shown) in cases where asingle main body design does not fit all nozzle types perfectly. In thatcase the subframe is designed to be fitted onto those nozzle types whichdo not fit perfectly and the main body introduced over the subframe. Thesubframe fills the space between the main body and the nozzle,compensating for the ill-fitting of the main body, and allowing moresecure attachment of the main body. It will be seen, however, that thehook-type arrangement, where suitable for the given nozzle type, allowsa reduction in the number of components to the system.

Referring now to FIGS. 9a and 9b a further variant of the collar portionaccording to the present invention is shown at 60. In particular thecollar portion 60 is arranged to receive a collar portion adapter 62.The adapter 62 is optional and only needs to be used for nozzles of afirst diameter, the collar portion 60 being suitable without the adapterfor nozzles of a second, larger diameter. Accordingly, in order toaccommodate all nozzle types only a single splashguard/collar portion 60is required, the adapter 62 being optionally included. As a resultmanufacturing costs are yet further decreased, in particular as only asingle component 60 having the required external finish is required, theadapter 62 only being further included for nozzles of the firstdiameter. As will be seen the adapter 62 includes projections 64 whichengage with recesses 66 in the collar portion 60. As a result theadapter 62 is held firmly in place. Any number of such projections 64may be used; however, to avoid moulding difficulties it is preferred tohave four projections 64 comprising two pairs projecting fromsubstantially opposite sides of the adapter 62.

Referring to FIG. 10, an alternative splashguard shape is shown forsplashguard 60. As will be seen the splashguard 60 is roughlyegg-shaped, the nozzle aperture being positioned eccentrically at thenarrower end. The splashguard 60 is positioned on the nozzle with thenarrower end lowermost, such that the majority of the splashguard 60extends outwardly and above the nozzle. As a result the splashguard 60still functions well but does not foul conventional "holsters" becauseit has no appreciable component extending below the nozzle.

It will be appreciated that and it is intended that, features describedwith reference to one specific embodiment can be adopted, whereappropriate, into other embodiments without departing from theinvention.

It will be seen that the invention thus allows simple modification of asingle component of an information display device allowing the device tobe placed on either of for example the two types of "ZVA" nozzles thatare currently widely in use. As mentioned above, the invention is, ofcourse, applicable in the case of any suitable nozzle, for example theOPW nozzle. In addition, because of the manner in which the protectivewindow is fitted into the main body of the assembly the removal or lossof the information display surface is prevented or discouraged otherthan by authorised personnel. It will be appreciated that the assemblycould also be used for mounting other items on the scuffguard of a fueldispensing device if desired. It will further be appreciated that thecollar could be suitably configured to be placed on the housing of afuel delivery device without a scuffguard in place. Although the"filling-in" portion is described as a splashguard in fact that partcould comprise simply the projection portion although the splashguardarrangement provides an advantageous combination of features, thesplashguard acting additionally as the "filling-in" portion.
